HTTP protocol ... set the time the page expires to be in the past.

Something like...

<?php
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Fri, 1 May 2007 12:00:00 GMT");
?>

 

Right?

Try

header( 'Expires: Mon, 26 Jul 1997 05:00:00 GMT' );
header( 'Last-Modified: ' . gmdate( 'D, d M Y H:i:s' ) . ' GMT' );
header( 'Cache-Control: no-store, no-cache, must-revalidate' );
header( 'Cache-Control: post-check=0, pre-check=0', false );
header( 'Pragma: no-cache' );

I used

header("Cache-Control: no-cache, must-revalidate");

header("Expires: Fri, 1 May 2007 12:00:00 GMT");

which works fine.
